decisions:
|
|
- "Derived 5 rows: one per PKG-0x success criterion from v1.0-ROADMAP.md Phase 5 (PKG-01..05). No extra historical-gap bonus rows — PKG-04 gap is recorded inside row 4 itself (not as a separate row) because the criterion wording covers both upload + embedding."
|
|
- "Row 2 (PKG-02 byte-level .intunewin conformance) is the STRONGEST row in the entire 7-phase Nyquist audit track. It cites 14 pytest byte-level assertions PLUS RTVAL-01 artifact-backed PASS on tenant rubis.fr (2026-04-13) with committed screenshots and the exact .intunewin package under test. The preamble explicitly calls out that RTVAL-01 initially FAILED and was fixed by commits 74535ea (HMAC over IV+ciphertext) + 7716246 (Detection.xml alignment with IntuneWinAppUtil.exe reference format) — this is the audit-trail equivalent of 'caught and fixed before real deployment'."
|
|
- "Row 1 (PKG-01 one-click .intunewin export) also cites RTVAL-01 but the success criterion is 'user can export'; the 'Intune accepts the package' piece is more directly owned by PKG-02. Row 1 therefore cites RTVAL-01 as supporting evidence without the structural-fix commentary (that belongs to PKG-02)."
|
|
- "Row 4 (PKG-04 icon upload + embedding) records the historical gap IN PLACE rather than flipping to fail-fix-v1.1. Phase 5 plan 02 shipped icon upload + storage only; Phase 6 (Wire Icon into .intunewin Export) added TestIntunewinIconInclusion which closes the embedding half. This mirrors the 08-02 row 6 (drivers/upload 500 historical gap closed by Phase 9 UX-01) pattern explicitly approved in the plan 08-02 methodology."
|
|
- "Row 3 (PKG-03 NinjaRMM ZIP) has no Phase 10 runtime evidence and does not need any — NinjaRMM packages are opaque ZIPs fed into the customer's RMM, there is no Microsoft format spec to defend against. Template-level + HTTP-level correctness via pytest is sufficient for Nyquist. Phase 11 rollout owns real NinjaRMM execution."
|
|
- "Row 5 (PKG-05 command preview) cites TestCommandPreview class + template IDs + 05-VERIFICATION.md truths 9+10+11. The Alpine.js copy-to-clipboard UX remains a Manual-Only Verification (listed in 05-VERIFICATION.md 'Human Verification Required #2') and was NOT exercised in Phase 10 — Phase 10 did not cover browser reactivity. The minor 'Uninstall copy' label cosmetic issue flagged in 05-VERIFICATION.md Anti-Patterns is noted as UX polish, not a correctness defect."
|
|
- "No historical-gap BONUS rows (unlike 08-02 row 6). PKG-04's gap is already the 'canonical' Phase 5 row 4, not a bonus row, because the success criterion itself covers both upload and embedding."

# Phase 08 Plan 05: Phase 5 Nyquist Audit Summary
|
|
|
|
**One-liner:** Audited Phase 5 (Package Export, PKG-01..05) against Nyquist rules and upgraded `05-VALIDATION.md` in place with a 5-row Nyquist Record where PKG-02 (byte-level `.intunewin` conformance) becomes the **first and only artifact-backed live-Intune-tenant runtime row** in the entire 7-phase audit track — citing RTVAL-01 PASS on rubis.fr after commits `74535ea` + `7716246` fixed the two structural defects (HMAC over IV+ciphertext, Detection.xml alignment) that caused the initial FAIL — and PKG-04's historical icon-embedding gap is recorded in place with Phase 6 closure (`TestIntunewinIconInclusion`) cited.
|
|
|
|
## What Shipped
|
|
|
|
- `.planning/phases/05-package-export/05-VALIDATION.md` now contains a `## Nyquist Record` section (placed above Validation Sign-Off, below Manual-Only Verifications).
|
|
- 5 rows: one per PKG-0x success criterion from `milestones/v1.0-ROADMAP.md` Phase 5 goal block (PKG-01..05).
|
|
- Every row has a non-empty Observable Check (pytest invocation) and a non-empty Evidence cell citing committed tests, source paths with line numbers, commit SHAs, 05-VERIFICATION.md truths, and — for PKG-01 + PKG-02 — Phase 10 `RUNTIME-VALIDATION.md` RTVAL-01 artifact-backed PASS.
|
|
- **Row 2 (PKG-02) is the strongest row of the entire 7-phase Nyquist track:** 14 byte-level pytest assertions in `tests/test_intunewin.py` PLUS artifact-backed tenant acceptance (screenshots `rtval-01-tenant-upload.png` + `rtval-01-app-assigned.png`, committed package `Copieur_2eme.intunewin`, tenant `rubis.fr`, test device `ARES-5CG5220YTM`). The preamble explicitly narrates the initial FAIL → root cause → fix → re-test PASS arc so the audit trail shows "caught and fixed before broad deployment".
|
|
- **Row 4 (PKG-04) records the icon-embedding historical gap in place** and cites Phase 6 closure via `tests/test_packages.py::TestIntunewinIconInclusion::test_intunewin_includes_icon` + `::test_intunewin_without_icon_succeeds`. Status remains `pass` — this mirrors the 08-02 row 6 (drivers/upload 500 → Phase 9 UX-01 closure) methodology.
|
|
- Frontmatter updated: `nyquist_compliant: false -> true`, added `nyquist_audited: 2026-04-13`, `nyquist_auditor: Claude (gsd-executor, plan 08-05)`.
|
|
- All historical sections (Test Infrastructure, Sampling Rate, Per-Task Verification Map, Wave 0 Requirements, Manual-Only Verifications, Validation Sign-Off) preserved verbatim. Sign-Off checkbox for `nyquist_compliant: true` ticked.
|
|
|
|
## Audit Outcome
|
|
|
|
| Status | Count |
|
|
|---------------|-------|
|
|
| pass | 5 |
|
|
| fail-fix-v1.1 | 0 |
|
|
| deferred-v1.2 | 0 |
|
|
| wont-do | 0 |
|
|
|
|
Phase 5 is Nyquist-compliant. Uniquely among the 7 v1.0 phases audited so far, Phase 5 row 2 (PKG-02) carries **artifact-backed** real-tenant runtime evidence via RTVAL-01 — no attestation-only caveat on this row. Rows 1 + 4 also benefit from RTVAL-01 as supporting evidence.
|
|
|
|
## Evidence Strategy Used
|
|
|
|
Priority order from CONTEXT.md honored:
|
|
|
|
1. **Test evidence** (preferred): 5/5 rows cite concrete pytest invocations. PKG-02 cites 14 byte-level assertions in `tests/test_intunewin.py` across 5 test classes (`TestOuterZipStructure`, `TestDetectionXml`, `TestEncryptedBlobLayout`, `TestCryptographicVerification`, unencrypted size). PKG-01/03 cite `tests/test_packages.py` (`TestIntunewinDownload`, `TestNinjaDownload`). PKG-04 cites both `tests/test_icon_upload.py` (upload half) and `tests/test_packages.py::TestIntunewinIconInclusion` (embedding half). PKG-05 cites `tests/test_packages.py::TestCommandPreview`.
|
|
2. **Commit/file-line evidence**: `imptune/api/packages.py` (get_ninja_package lines 49-94, get_intunewin_package lines 97-158), `imptune/generators/intunewin_builder.py` (build_intunewin, AES-256-CBC, HMAC-SHA256, Detection.xml), `imptune/api/icons.py` (Pillow validation lines 41-74), `imptune/api/pages.py` (lines 102-103 command context), `imptune/templates/printer_detail.html` (install-cmd/uninstall-cmd IDs lines 31/40, export hrefs lines 49-50). Commits cited: `a31c71e` (05-01 RED), `dd6cedf` (05-01 GREEN), `d8ce223` (05-02 icon RED), `f9e13ba` (05-02 icon GREEN), `f96ea6f` (05-02 UI), and critically `74535ea` + `7716246` (the two structural fixes that flipped RTVAL-01 from FAIL to PASS).
|
|
3. **Dated manual-check evidence**: 05-VERIFICATION.md (2026-04-10, 11/11 truths VERIFIED) referenced per-row for cross-traceability.
|
|
4. **Runtime evidence (artifact-backed)**: Phase 10 `RUNTIME-VALIDATION.md` RTVAL-01 PASS cited on rows 1 + 2 + 4 — with committed screenshots and package, no attestation-only caveat. Plan 10-03 sign-off (commit `cd2df1e`) cited as formal acceptance.
|
|
|
|
No row relied on "code looks right" or attestation-only runtime — every row has a concrete pytest invocation, and PKG-02 additionally has artifact-backed real-tenant proof.
|
|
|
|
## Cross-Reference with 05-VERIFICATION.md
|
|
|
|
`05-VERIFICATION.md` (dated 2026-04-10) enumerated 11 observable truths covering PKG-01..05. The Nyquist Record collapses these to 5 rows (one per criterion) as follows:
|
|
|
|
- Row 1 (PKG-01) ← truth 2 (intunewin endpoint), truth 5 (build_intunewin native), truth 3 (404/422 error paths)
|
|
- Row 2 (PKG-02) ← truth 5 (Python-native no subprocess) + 14 `tests/test_intunewin.py` byte-level truths + RTVAL-01 artifact evidence
|
|
- Row 3 (PKG-03) ← truths 1 (ZIP contains install + drivers) + 4 (DEFLATE + folder structure)
|
|
- Row 4 (PKG-04) ← truths 6+7+8 (icon upload/validation/replace) + Phase 6 TestIntunewinIconInclusion (icon embedding half, gap closure)
|
|
- Row 5 (PKG-05) ← truths 9 (command strings rendered) + 10 (copy buttons present) + 11 (export links present)
|
|
|
|
The "Human Verification Required" items from 05-VERIFICATION.md map as follows:
|
|
- #1 ".intunewin byte-level Intune compatibility" → **CLOSED** by RTVAL-01 artifact-backed PASS (row 2)
|
|
- #2 "Alpine.js copy-to-clipboard UX" → still Manual-Only (row 5 Notes), owned by Phase 11 rollout visual polish
|
|
- #3 "HTMX icon upload response swap" → still Manual-Only (row 4 Notes), owned by Phase 11 rollout visual polish
|
|
|
|
## Artifact-Backed Evidence Highlight (Key Point for 08-08 Rollup)
|
|
|
|
Per STATE.md 2026-04-13, **Phase 10 RTVAL-01 is the only artifact-backed runtime check** across the entire Phase 10 runtime half (RTVAL-02/03/04 are all attestation-only, 3 consecutive). This Phase 5 audit is therefore the **unique beneficiary** of strong real-tenant runtime evidence in the entire 7-phase Nyquist track. When 08-08 rolls up the milestone Nyquist summary, it should note:
|
|
|
|
- Phase 5 PKG-02: **artifact-backed runtime** (committed screenshots + package + tenant confirmation)
|
|
- Phase 5 PKG-01 + PKG-04: artifact-backed runtime via PKG-02's transitive coverage (same builder path)
|
|
- Phase 1 row 14: artifact-backed via RTVAL-01 tenant ingestion (dev environment + infra check)
|
|
- All Phase 4 SCRPT-0x rows: attestation-only runtime (RTVAL-02/03/04)
|
|
- All Phase 2/3/6/7 rows: no Phase 10 runtime coverage at all (purely template/HTTP level)
|
|
|
|
The two fix commits `74535ea` + `7716246` are the most important artifacts this audit surfaces — they represent real defects that real-Intune testing caught and that the team fixed before broad rollout. This is exactly the workflow Nyquist validation exists to produce.
|
|
|
|
## Deviations from Plan
|
|
|
|
**None.** Plan 08-05 executed exactly as written. Single task, single file edit. The plan explicitly instructed: *"For byte-level .intunewin conformance: cite commits 74535ea and 7716246 plus Phase 10 RTVAL-01 PASS. This is the only strong artifact-backed runtime row in Phase 10 per STATE.md."* — done on row 2. The plan also instructed to consult `tests/test_intunewin.py` and `tests/test_packages.py` for test names — done via Grep to confirm `TestOuterZipStructure`, `TestDetectionXml`, `TestEncryptedBlobLayout`, `TestCryptographicVerification`, `TestNinjaDownload`, `TestIntunewinDownload`, `TestCommandPreview`, `TestIntunewinIconInclusion`.
|
|
|
|
No Rule 1-4 deviations triggered. No auth gates.
|
|
|
|
## Authentication Gates
|
|
|
|
None.
|
|
|
|
## Task Commits
|
|
|
|
1. **Task 1: Build Phase 5 Nyquist Record and upgrade 05-VALIDATION.md** — `cecf917` (docs)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `.planning/phases/05-package-export/05-VALIDATION.md` — added `## Nyquist Record` section (5 rows, preamble, outcome), updated frontmatter (`nyquist_compliant: true`, `nyquist_audited`, `nyquist_auditor`), ticked Sign-Off checkbox
|
|
- `.planning/phases/08-nyquist-validation-track/08-05-SUMMARY.md` — this file
|
|
|
|
## Next Phase Readiness
|
|
|
|
- 5/8 plans of Phase 08 complete (08-01..08-05 audited: Phase 1, 2, 3, 4, 5)
|
|
- Remaining: 08-06 (Phase 6 gap-closure audit), 08-07 (Phase 7 gap-closure audit), 08-08 (milestone rollup index)
|
|
- 08-06 should be quick: Phase 6 is a single-plan gap-closure phase that closed PKG-04 icon embedding, already referenced in this audit's row 4
|
|
- 08-08 rollup should explicitly highlight PKG-02 as the strongest artifact-backed row in the track
|
|
|
